- My invention relates to lighting units and has particular relation toa Supporting device for such units.

Lighting units have been devised whereby the sockets, the lamps'and theglobes are so arranged and supported that the globes may be removed fromthe supports without dis turbing the sockets. Generally, they globesv ofsuch lighting units are provided with cylindric'al openings in theirupperv portions,

} and the supporting'stand ardsrare provided with two or more projectingfingers to sup- 7 port the globes by projecting beneath suit ableflanges of the gl obes. When the globes are in engaged position,supporting canopies or like membersrest uponthem to prevent them fromtilting and from being disengaged from the supports.

However, such devices are so constructed that the globes are not easilyremoved by a single operator, and consequently, breakage of the globesfrequently occurs.

My invention is intended to eliminate these 7 and other difficulties andto provide animreadily be manipulated the globe and disassembly oftheunit.

proved supporting device. Therefore, an object of my invention is to.provide a sup-. porting device for a li hting unit which may to permitremoval of Another object of my invention is to provide a simple,inexpensive, strong and durable device. a

Other objects of my invention will appear in the following descriptionof my device, taken in conjunctionwith the drawings.

Referring to the drawings, in which like figures indicate like parts, VV

Fig. 2 is a side view, partly in elevation and partly in section, of mydevice with the canopy in a disengaged position and showing the globebeing mounted upon the supporting device. p

Referring to the drawings, the supporting member l is here shown asnatube having a 19 29. seriai 371,765 V the tube or pipe byimeansgofanipple 4Q and a bracket .5, the'centralportionrof which; en? tgagesthenippleand the'louter'endsofwhich are fastened vscrews6.

:1 If no f rtherstructure werefprovided,"the

globe might eventually become disengaged from the globe support,'so thata canopy 14, which is'preferably of bell-shape and has. a lower flange15,- is provided with an opening 16' at its center so thatit-maybe slidably mounted on the standard 1 and may be moved up and down or tiltedthereon; When the canopyfisvin itsrlower orengaging position,

globe andsupport In its raised .position',:,-the canopymay be tilted,and the lower edgeof the flange ,15

may be engaged by one oftheprojectio'ns :11

to hold the canopy in its raisedposition'while theglobe'is beingremoved.

The devices of the-prior ,art have: been so sary' for the operator: tohold the 1 canopy in arranged and constructed that it was neces itsraised or disengaged positionwith one support.

It is apparent that other modifications of my device may bemade; forinstance, the. support 7, instead of being a flat strip of metal, maybeapmemberof cup shape. Instead of the projections- 11, which-are adaptedto coact with the flange 15, projections may be placed on the inside ofthe'canopy to coact with suitable depressed portions or open- "ings inthe support. These and othermodifications maybe made by those skilled inthe art without departing fromthe spirit and scope of my invention, asset forth in the ap pended 'claims..

tacle adapted'to be connected to an energiz- 1ng source, a globe havingan openlng 1n its upper part for engaging the globe support,

a canopy slidably mounted on the supporting member to hold the globe inplace on the globe'support, a locking- "means for holding the.canopyin-its engaged position,-a nd coacting means on the globe supportand canopy for holding the canopy in a raised disengaged position."

In testimony whereof, have hereunto subscribed my name this 7th day ofJune 1929. OSCAR WERNER.
